SPECIFICATION forming part of Letters Patent No. 640,638, dated January2, 1900. Appnmanfiieaooateit,1899. serai No. 732,691, (remodel.)

To all whom t may concern:

Beitknown that I, ALBERT C. DIEHL, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inHose-Couplings; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame. f

My invention relates to improvements in hose-couplings, more especiallyto that class of hose-couplings in which a ball-valve is employed toprevent the escape of air, steam, or other fluid when the coupling isuncoupled.

In order to more fully describe my invention, reference will be had tothe accompanying drawings, in which- Figure l represents a sideelevation of my improved coupling. Fig. 2 represents an end elevation ofthe same. Fig. 3 represents a section on the lineAB in Fig. 2. Fig. 4represents a section taken on the line A B in Fig. 2, showing one end ofthe hose removed. Fig. 5 represents a section taken on the line C D inFig. 4. Fig. 6 represents one of the hose ends in side elevation. Fig.`7represents the same in end elevation. Fig. 8 represents a side elevationof a modified form of my coupling. Fig. 9 is an end elevation of thesame. Fig. 10 is a section on the line A' B in Fig. 9. Fig. ll is asimilar section showing one of the hose ends removed. Fig. 12 is asection on the line C D' in Fig. 11. Fig. 13 is a side elevation of oneof the hose ends, and Fig. 14 is an end elevation of the same.

Similar letters and numerals refer to similar parts throughout theseveral views.

My improved coupling consists of two hose ends 1, having two projectinglugs b on their larger ends and having attached to each, as at 10, alatch 8, upon which a spring 9 normally acts to force outward.

2 represents a hollow sleeve having an annular internal groove c neareither end of its ends and two notches d in each end, also two passagesct in each end, which lead into said annular grooves c. Into this sleeve2 is forced a valve-box 3, which becomes practically a part of thesleeve. This valve-box is hollow and capped at its open end 4. Throughboth ends of the valve-box a hole 1l is drilled, around the edge ofWhich a valve-seat packing-ring 6 is forced and against which the` steelball-valve 5, contained in the valve-box 3, seats itself to cut off theflow of iiuid.

A plug g extends across the inner ends of the hose ends, and when thesaid hose -ends are inserted in the sleeve 2 the plug g extends into theopening at the end of the valve-box and lifts the ball-valve off itsseat.

The action of the coupling is as follows: The hose end 1 being fastenedin the hose and the sleeve2, containing the valve-box 3 and theball-valve 5, connected with the hose end, as shown in Fig. 3, the iiuidunder pressure coming through the hose in the hose end l entersthevalve-box 3 by the passage f through the valve-seat and forces thevalve-against the opposite valve-seat, thus closing the passage andpreventing the escape of iiuid. A second hose end, which is a duplicateof the first, is fastened into the hose which is to be connected. Tovmake the coupling, the

end of the loose piece of hose having the hose end l fastened therein isbrought into line with the sleeve 2, the position of which with regardto the hose end lis such that the lugs b Will pass through the openingainto the annular groove c, when by turning the loose hose end the latch8 will catch into the notch d, thus locking the coupling'. As the hoseend l is pushed into the sleeve 2 the plug g forces the ball-valve 5 offits seat 6, thus allowing the fluid to pass through the opening f intothe new section of hose. To uncouple the joint, the latch 8 is depresseduntil it will allow the hose end 1 to be turned. The end is then turneduntil the lug b registers with the opening d, when the hose end l may bepulled out. As the hose end l is drawn out the fluid presses theball-valve 5 against the seat 6, thus closing the passage and stoppingthe iiow.

The modification shown in Figs. S to 14 differs from the constructionshown in Figs. 1 to 7, inclusive, in some respects, which will beapparent, as follows: The hose ends l', provided with two projecting lugs b' on the larger ends and having attached to each, as at 10', thelatch S', upon which a spring 9 acts, tend- IOO ing to force the latchoutward, (illustrated in Figs. lO and 11,) are all practically the sameas the construction shown in Figs. 3 and 4. The hollow sleeve 2 has anannular internal groove c near either of its ends and a notch d in eachend and also two passages a' in each end which lead into the annulargroove c. In this sleeve is forced the valve-box 3', which becomespractically one piece with the sleeve. This valve-hon is hollow andcapped at its open end; hut the construction thereof diers somewhat fromthe valve-box 3, (shown in Figs. 3 and Li,)and it is in connection Withthis principally that the difference lies.

Through each end of .the valve-box 3 a holev is drilled, which forms thepassage f'. These holes are drilled eccentric tothe center of thevalve-box and are diametrically opposite each other. Around the edges ofthe said holes a valve-seat packing-ring 6 is forced and against whichthe steel hall-val ve contained in the valve-box 3, seats itself to cuton the iiow of iluid. A pin e is fastened eccentric in each of the hoseends l in such position that when the hose ends are inserted in thesleeve 2the pin 4 will rest in the position fc (see Fie". l2) in thegroove g in the valvebox 3'. Then by turning the hose end l the pin ewill move to the position y', Fig. 12, which is near the center of thepassage f. The action of the coupling in this instance is as follows:The hose end lt being fastened in the hose, and the sleeve 2', containedin the valve-hoX 8', connected with the hose end 1, as shown in Fig.'1l, the fluid under pressure coming through the hose and the hose end lenters the valvebox 3 by the passage f in the valve-seat and forces thevalve against the opposite seat, thus closing the passage and preventingthe escape of fluid, as hereinhefore described with reference to Figs. lto 7. A second hose end, which is a duplicate of the first, is fastenedinto the hose which is to he connected. To effect a coupling, the loosepiece of hose, having the hose end 1' fastened therein, is brought intoline with the sleeve 2', the position of which with regard to the hoseend l is such that the lugs b will pass through the openings a' into theannular groove c and the pin Ll into the groove g', when by turning thehose end the latch S will catch in the notch d', thus lool;- ing thecoupling. As the hose end l is turned the pin Ll moves from its positionm' into the groove g' to the position y in the passage f'. In so doingthe pin e comes in contact with the hall-valve 5' and forces the sameoli its seat,

thus allowing the iiuid to pass through'the passage f into the newsection of hose. To disconnect the coupling, the latch S is depresseduntil it will allow the hose endl' to be turned. The end is then turneduntil the lug t registers `with the passage a', When the hose end may hepulled out. As the hose end l' is turned the pin 1' moves y,from theposition y in the passage f to the position fr in the groove g',allowing the ball-valve 5l to assume its original position, closing thepassage f and cutting oft the flow of duid.

In some respects the form of coupling shown in Figs. 8 to la isadvantageous over the coupling 'shown in Figs. l to 7,and this advantageresides chieliy in the fact that the lugs h engage in the annular groovec before the valve opens, thus making the operation of coupling randnnconpling much easier and overcoming the tendency which the pressurehas in the latter forni of forcing the loose end out.

I do not Wish to limit myself to the precise details hereinheforedescribed and as shown in the drawings, as man y in odilications mightbe made Without departing from the spirit of my invention.

Having thus fully described my said invention, whatlclairn, and desireto secure by Letters Patent of the United States, is-
